Enabling Docker Remote API on Ubuntu 16.04

• Find out where the docker. service file is located:

• systemctl show –property=FragmentPath docker

• Display docker.service configuration using following command.

• cat /lib/systemd/system/docker.service

•  Please note we will be modifying ExecStart Variable

•  Modify the ExecStart variable using following procedure

•  Open docker.service file using following command

•  sudo vim /lib/systemd/system/docker.service

•  Press Alt I to insert the text.

• Navigate to the row for ExecStart and add following

•  ExecStart=/usr/bin/dockerd -H 0.0.0.0:2375 -H fd://

•  To save Press Esc + wq!

•  Verify configuration using following command

•  cat /lib/systemd/system/docker.service

•  Now update SystemD and restart Docker by running following 2 commands

• sudo systemctl daemon-reload

• sudo systemctl restart docker

• Verify docker is listening on any IP and the port specified

• systemctl status docker

•  Now you should be able to access Docker API remotely i.e. You should be able to add host in Management UI (Portainer – Please refer my previous blog)

• Once Host is Added you can view it under Dashboard
